largefile

Description

A large file is a regular file whose size is greater than or
equal to 2 Gbyte ( 231 bytes). A small file is a regular
file whose size is less than 2 Gbyte.

Large file aware utilities

A utility is called large file aware if it can process large files in
the same manner as it does small files. A utility that is
large file aware is able to handle large files as input and
generate as output large files that are being processed. The exception is where
additional files are used as system configuration files or support files that
can augment the processing. For example, the file utility supports the -m
option for an alternative “magic” file and the -f option for a
support file that can contain a list of file names. It is unspecified
whether a utility that is large file aware will accept configuration or
support files that are large files. If a large file aware utility
does not accept configuration or support files that are large files, it
will cause no data loss or corruption upon encountering such files and will
return an appropriate error.

Large file safe utilities

A utility is called large file safe if it causes no data loss or
corruption when it encounters a large file. A utility that is large
file safe is unable to process properly a large file, but returns
an appropriate error.
